2 Basic information Number of project years* 3 Calculated project time* Project title (Swedish, max 200 characters)* Vargens återkomst konsekvenser för hållbar användning av naturresurser Project title (English, max 200 characters)* The return of the wolf consequences for sustainable use of natural resources Popular scientific description (Swedish) (max 4500 characters)* Stora rovdjur har världen över återkoloniserat stora delar av sina forna utbredningsområden under de senaste årtiondena. Ny forskning har visat att stora rovdjur under vissa omständigheter kan ha oproportionerligt stor betydelse för ekosystemens funktion. Genom att rovdjur har stor potential att påverka alla nivåer i näringspyramiden såsom bytesdjurens numerär och beteende och via bytesdjurens fördelning i landskapet även den lägsta nivån i systemet (vegetation). Återkolonisering av stora rovdjur har till och med angetts som ett verktyg för framgångsrik restaurering av ekosystem. Huvuddelen av studierna har dock genomförts i ett fåtal välkända områden i Nordamerika som har låg grad av mänsklig påverkan, d.v.s. oftast i nationalparker. Av denna anledning har flera av dessa studier kritiserats för att dra alltför långtgående slutsatser och att överdriva betydelsen av stora rovdjurs återkomst ur en global synvinkel. Återkolonisering av stora rovdjur, inklusive varg, sker också i Europa men en viktig skillnad jämfört med de flesta tidigare studerade områdena i Nordamerika är att de flesta områden i Europa är under kraftig mänsklig påverkan genom t.ex. jakt och skogsbruk. I Sverige har vargen, efter en frånvaro på över 150 år, återkolloniserat delar av dess forna utbredningsområde. De nuvarande förhållandena i Sverige skiljer sig på flera viktiga punkter från många tidigare studerade områden. En av dessa är att människans jakt på vargens viktigaste bytesdjur (älg) har en lång kulturell tradition och har ersatt predation av varg som en viktig begränsande faktor på älgstammen. I Sverige är älg det viktigaste jaktbara viltet med cirka skjutna älgar per år och är en årlig höjdpunkt för många av de jägarna. En annan viktig skillnad är att det svenska skogsekosystemet är starkt påverkat av det kommersiella skogsbruket. Omfattande betesskador av klövvilt, främst älg, på skogsplantor har under de senaste decennierna lett till en intensiv konflikt mellan markägare och jägare vilket i många områden har lett till en avsiktlig minskning av älgstammens storlek genom ett ökat jaktuttag. Den senaste tidens snabba ökning av vargstammen i delar av Sverige har resulterat i starka konflikter med allmänheten. En av de viktigaste bakomliggande orsakerna till konflikterna är att vargen genom sin predation på älg konkurrerar med människan genom jakten på framförallt älg. Att denna konkurrens kan vara betydande framgår av den kraftiga minskningen av jaktuttaget av älg som har skett i delar av vargens utbredningsområde. Under antagandet att detta mönster i jaktuttag speglar en verklig förändring i älgstammens storlek kan vi också förvänta oss att detta medför en inverkan på den lägsta nivån i näringskedjan (vegetationen). Detta kan i så fall medföra stora konsekvenser för den biologiska mångfalden av olika betesväxter (rönn, asp, sälg, ek) och även för skadenivåerna på kommersiellt värdefulla skogsplantor (tall). Med tanke på de mål som gäller för bevarande av hotade arter som anges i EU-direktiven, den komplicerade juridiska processen som har åtföljt vargen, och möjligheten till att begränsa vargpopulationen med jakt, är det fullt möjligt att både antalet vargar och populationens utbredning kommer att fortsätta öka. Huvudsyftet med det föreslagna forskningsprojektet är att förbättra förståelsen av effekterna av en växande vargpopulation och vilka konsekvenser det kan få för regleringen av älgstammen, jakten på älg, omfattningen av skador på kommersiellt värdefulla trädarter, och för funktionen och den biologiska mångfalden i ekosystemet. Vi avser att analysera tidsserier av data på vargens närvaro och hur detta påverkar älgarnas beteende och rumsliga fördelning, älgstammens och jaktuttagets storlek, samt omfattningen av betesskador från älg på skogsplantor på tre olika geografiska nivåer. Detta innefattar analyser på den lokala nivån (skogsbestånd), på regional nivå (älgförvaltningsområden, länsnivå), samt att beräkna och kvantifiera den ekologiska betydelsen av varg och sätta detta i relation till betydelsen av ett annat viktigt rovdjur nämligen människan i ett land (Sverige) med en hög grad av mänsklig påverkan. Det föreslagna forskningsprojektet har direkta kopplingar till flera samhällsmål inklusive 1) ökad biologisk mångfald, 2) minskning av skogsskador av vilt, 3) uppnå gynnsam bevarandesstatus för varg, och 4) ett långsiktigt hållbart nyttjande av vilt som resurs. 2 / 33

3 Abstract (Swedish) (max 1500 characters)* Under de senaste 20 åren har vargen återvänt till det svenska skogsekosystemet. Människa, älg och varg påverkar alla ekosystemet via skogsbruk, predation och bete vilket påverkar den biologiska mångfalden och flödet av biomassa mellan trofiska nivåer. Syftet med detta projekt är att förbättra kunskapen om ett återkolloniserande rovdjur (varg) och vilka konsekvenser det kan få för 1) regleringen av stora växtätare (älg), 2) jaktuttag, 3) skogsbruket och 4) den biologiska mångfalden. Genom att använda tillgängliga uppgifter om 1) älgpopulationernas storlek (spillnings- och flyginventering, jaktdata), 2) vegetation (betestryck/skadeundersökningar), 3) vargtäthet (predation) och 4) skogsbruk (biomassauttag), kommer vi att visa hur de olika aktörerna samverkar och påverkar varandra. Med den kunskapen kommer vi att kunna föreslå strategier för att a) minimera skogsskador, b) anpassa jaktuttagets storlek till ett system med två stora rovdjur (människa och varg) och c) vad som krävs för att uppnå ekologisk funktionalitet för varg. Det föreslagna forskningsprojektet är direkt relaterad till ett hållbart nyttjande av naturresurser genom att koppla det viktigaste jaktbytet i Sverige (älg), till skogsproduktionen (en av de viktigaste svenska industrierna) samt till återkoloniseringen och bevarandet av en kontroversiell och hotad art (varg). Genom att involvera olika intressegrupper kommer vi att kunna diskutera den bästa användningen av tillgängliga data och lämplig användning av dessa. Abstract (English) (max 1500 characters)* During the last 20 years the wolf has returned to the Swedish forest ecosystem. Humans, moose and wolves all affect the ecosystem by forest management, harvest, predation and browsing, and as a consequence they all may impact on biodiversity and flow of biomass between trophic levels. The objective of the project is to improve the knowledge of a returning top predator (wolf) and the consequences it may have for 1) the regulation of large herbivores (moose), 2) moose harvest, 3) forestry, and 4) biodiversity. By using available data on 1) moose (pellet counts, aerial surveys, harvest data), 2) vegetation (browsing/damage surveys), 3) wolf density (predation), and 4) forestry (biomass outtake), we will show how the different players of this system interact and affect each other. With that knowledge at hand we will be able to suggest strategies to a) minimize forest damage, b) adapt harvest size to a system with two top-predators (humans and wolves), and c) attain the ecological functionality of wolves. The proposed research project directly relates to the sustainable use of natural resources in terms of linking the most important game species in Sweden (moose), to forest production (one of the most important Swedish industries), and to the conservation and re-colonization of an iconic and endangered top predator (wolf). By involving stakeholders at an early stage we will be able discuss the best use of available data and how to prioritize to optimize the outcome of the project. 3 / 33

4 Research programme Specific aims and objectives of the proposed project and a background description containing an overview of the research area, including key references (max characters)* Context, objectives and relevance The wolf-moose-human-forest dilemma The Swedish ecosystem is heavily affected by human impact mainly through an intensive forest management and harvest of ungulate populations. Forest management is one of the most important and valuable commercial industries in Sweden 1 and game hunting has a long cultural tradition and constitute both great economic (estimated to 3.1 billion on an annual basis) and recreational value 2,3. During the last years the number of key players has increased in large parts of the Swedish forest ecosystem, now also including wolves in addition to moose and humans. Humans, moose and wolves all directly and indirectly affect the forest ecosystem (e.g. biodiversity and the flow of biomass between different trophic levels) by forest management, harvest, and predation on moose, (Figure 1). Moose affect the system by browsing and can by selective foraging affect both biodiversity and damage levels on commercially valuable forest plants 4,5,6. Wolves may affect the ecosystem both through the impact on population size and behavior of their prey 7. As a consequence prey spatial distribution and the intensity of browsing may also be affected 8 resulting in altered damage levels on forest plants. Finally, humans exert a strong impact on all species and trophic levels of the ecosystem primarily through hunter harvest and changes of habitat (e.g. forestry and silviculture). Recent conservation policy has resulted in a rapid growth and geographical expansion of the wolf population and with a population density that currently is close to biological saturation in some regions of Sweden 9, i.e. territories bordering each other (Figure 2a-c). In some of these high density wolf areas moose harvest has been reduced with more than 50% (Värmland) only during the last four years (Figure 3) and are likely to be further reduced within the near future. With an expected continued wolf population growth this development may become the norm even over much larger areas and will have large consequences for the cultural tradition of moose harvest and for the use of this natural resource. In addition, wolves through their predation on moose, are also likely to have important indirect effects on the vegetation community in terms of both biological diversity and damage levels to commercially valuable forest plants. Although both wolves and moose have been thoroughly studied in Scandinavia there is yet a limited understanding on how these key players interact and affect each other at the ecosystem level. In particular, the relative importance of wolves and humans for the spatial distribution and population size of moose, and to what extent these interactions may impact on plants and forest biodiversity are currently not known. So far, most studies investigating the effect and functional role of returning top predators have been performed in national parks and in other areas with low human impact, i.e. very different from the Swedish ecosystem. Objectives and gain of knowledge The main objective of the proposed project is to improve our understanding of the effects of the return of a top predator (wolves) and the consequences it may have for; the regulation of a key browsing ungulate (moose), the human harvest of moose, the harvest of commercially valuable plant species and the biodiversity of the boreal forest ecosystem. The results from this project will increase our understanding on: 1. the effect of wolves on the local (forest stand level) moose distribution pattern and its potential effect on the browsing and damage to commercially valuable forest plants, 2. the effect of wolf predation on the harvest yield of moose on a regional level (counties), 3. to what extent wolf predation may result in large-scale (counties) changes in moose density that in turn may result in altered browsing levels on commercially valuable forest plants (coniferous and deciduous trees), and 4. the relative impact of one new top predator (wolves) in relation to another common top predator (humans) in a forest ecosystem with a high degree of human impact. This knowledge can be applied in the conservation and management in terms of: i. how forestry practices could adapt to minimize damages made by moose, ii. how harvest size of moose needs to be adjusted to allow a sustainable harvest in the future, and iii. how various wolf population sizes and density can result in effects on more than one trophic level, promoting biodiversity and attaining different levels of ecological functionality. 4 / 33

5 Importance of the project Because 1) forest damages made by moose to commercially valuable forest plants is responsible for high economic losses on an annual basis 3 within one of the most important and valuable commercial industries in Sweden 1, and 2) moose is a valuable game species, there is a strong incentive to strive for a better understanding of the relative role of the interacting key players within the Swedish forest ecosystem. The proposed research project relates to several objectives of the society including 1) increased forest biodiversity 10, 2) reduction of forest damages by ungulates 11, 3) attaining a viable population of wolves 12, and 4) a sustainable use of moose populations 13. The probability of success of this project is very high, because most data is already at hand. The applicants have all a history of working with large carnivores and ungulates and related research questions. Håkan Sand has a long experience working with population ecology of both moose and wolves, Camilla Wikenros has an expertise in trophic cascades and top down effects from large carnivores, and Johan Månsson has focused his research on browsing damage from large ungulates at different spatial scales. An existing network of stakeholders are already identified and their organizations will be linked to the project as a reference group.

Description of the project including a summary of the structure, theory, methods, performance and a plan for scientific deliverables (max characters)* Solving the dilemma - from forest stands to regional and national scales Structure of the research project Our research will be structured at three different geographical scales; local, regional and national. On the local scale (forest stand) we will test the hypothesis that wolf presence results in a behavioral response by moose that has consequences for their spatial distribution and in turn also on the spatial pattern of browsing and damages to commercially valuable forest plants. We will use a long-term dataset on distribution of moose (pellet group counts) and browsing intensity from the Grimsö Wildlife Research Area (GWRA) combined with data from VHF/GPS-collared wolves and moose. On the regional scale (county) we will quantify how the presence of wolves has affected moose density, harvest, and the pattern of forest damages made by moose to commercially valuable forest plants (especially Scots pine). Data from the County Administrative Boards from moose management units will be used to test the hypothesis that wolf density and distribution is spatially and temporally linked to density of the moose population and therefore also to the size of moose harvest. We will then test if the variation in moose density can be linked to the level and pattern of forest damages. 5 / 33

6 On the national scale (current and future wolf distribution area) we will model the potential impact of the recolonizing wolf population on forest biodiversity via changes in ungulate population size. We will apply different scenarios of future wolf population development and size for a region predicted to constitute the main distribution area for wolves in Sweden. Based on these scenarios, we will compare the estimated mortality rates on the ungulate prey species resulting from wolf predation with a sustainable human harvest. These results will be used to quantitatively compare the importance of wolfinduced changes of ungulate populations and their potential effect on commercially valuable forest plants to that resulting from modern forest management. Theory - trophic cascades Along with the recent re-colonization by large terrestrial carnivores 1,2 a number of studies have casted new light on the importance of top predators for biodiversity and function of terrestrial ecosystems 3,2. In particular, their potential and realized effect on other trophic levels of the ecosystem, i.e. trophic cascades 4, has received much attention (reviewed in 2,3 ). These trophic cascades may be either of a direct nature, i.e. affecting the vegetation through a reduction of herbivore numbers through predation, or indirect, i.e. by effects on vegetation through behavioral adaptions of prey as a response to the mere presence of predators 5,6. As a result of the many studies presenting evidence for the effects of top predators on other trophic levels, reintroductions and re-colonization of large carnivores are being justified as a tool for successful ecosystem restoration 7,8. So far, the vast majority of these studies has been localized to a few well known areas, mainly national parks from which it has been claimed that large carnivores in general, and wolves in particular, may have a disproportionally large effect on several trophic levels, and thereby have the potential to significantly affect ecosystem structure and function 2,9,10,11. However, these studies have been criticized for making too far conclusions and for overemphasizing the importance of large predators comeback to the ecosystem 12,13,14. In fact, it is has been recognized that the effect of top predators is context dependent 7,8. For example, predation is not likely to be an important structuring force in the ecosystem when prey abundance is not limited by predation, or when the effect of predation does not extend beyond the level of prey 7. Also, the productivity and density of prey populations relative to the carrying capacity of the environment appear to be important for the extent to which predators will be able to limit the abundance of prey 7, 15, 16. Finally, even if predation does exert important impact on prey populations, these effects do not always propagate to lower trophic levels or have a significant impact on ecosystem processes. As a consequence, extrapolation beyond regions or across time periods may not be justifiable 8. Re-colonization of large carnivore species including wolves also occurs in Europe 1 but unlike most previously studied areas in North America, the carnivores in Europe return to landscapes under heavy anthropogenic influence, with large variation in primary productivity, and with the size of national parks small relative to the areas used by large carnivores (particularly wolves) 17,18. Because of these differences in land use there is an increasing need to advance our knowledge of the potential effects of re-colonizing large carnivores in areas with high intensity of anthropogenic land-use 19,20. Sweden after wolf colonization In Sweden moose is the most important game species with approximately moose harvested annually 21. The moose hunt is an annual highlight to many of the hunters 22 with the majority of the public being favorable towards a sustainable use of moose and deer meat 23. However, the large scale effects of moose browsing resulting in damages to forest plants has during the last decades resulted in an intense conflict between forestry and hunters 24 and has led to a management aiming at reducing moose population size in many areas 25,26. Another controversy involves the recovery of the wolf into the fauna of Sweden 27. One of the key conflicts involves competition with humans for game species, mainly moose 28,29. The conditions in Sweden are very different from many protected areas mainly because hunting has a long history and has during the last centuries replaced predation by top predators as the main regulating factor of the moose population. 6 / 33

7 The recent increase in the wolf population seems to further have resulted in a reduced number of harvested moose (Figure 3 and 4). If this pattern is indicative of a true change in moose population size we may also predict an impact on the next trophic level with consequences for the biological diversity (increase) and damage levels to commercially valuable forest plants (decrease). Given the conservation goals, e.g. stated in the EU-directives, a future wolf population will most likely expand to a larger geographical area. This further highlights the need of research on the effects of wolf recovery on several trophic levels of the ecosystem. Performance and methods A. Local scale - moose distribution, behavior and forest damages We will test the hypothesis that the mere presence of wolves results in behavioral adjustments of moose as an adaptive strategy to reduce the risk of predation. These behavioral adjustments include individual traits such as fine-scale habitat selection, home range use, and philopatry (remaing in the same area after the arrival of wolves) and may have consequences for pattern of moose browsing and damages at the level of the forest stand. In 2004 wolves established a territory covering roughly half of the GWRA (Figure 5) which offers a unique opportunity to compare moose browsing pattern and moose distribution both before and after wolf re-colonization as well as inside/outside the wolf territory. Response variables; 1) intensity of moose browsing on the main forage species (birch, pine, aspen and Salix spp.) and 2) moose density and distribution (pellet groups) have been annually collected (long-term, ) at 600 permanent sample plots systematically distributed over the ha study area (Figure 5). The collected data also includes background information of forest age, type and composition over the same area (GIS-data). In addition, we have access to data on moose movements with high spatial and temporal resolution from 35 GPS-collared moose and 4 adult wolves from two territories partially covering the GWRA during and 65 VHF-collared moose during Resource Selection Functions will be used to test whether wolf predation risk (wolf utility distribution) and duration (number of years since establishment) influences fine-scaled habitat use. General linear mixed models (GLMM) will be used to relate home range size, and philopatry of moose to wolf presence. By relating the spatial variation of browsing intensity to habitat parameters, moose density (pellet group counts), snow depth and wolf predation risk the relative importance of wolves on patterns of moose browsing can be evaluated. B. Regional scale - moose population size and damage levels of forest plants We will use hunter harvest statistics before and after wolf establishment (20 years) from moose management units within 5 counties (S,W,X,T,U) to investigate the hypothesis that 1) wolf presence and duration will result in a reduction in the size of the moose population and/or reduced human harvest, and 2) the predator-induced reduction in moose density/harvest can be linked to similar changes in browsing intensity and damage levels to commercially valuable forest plants. For hypothesis 1 we will use harvest size, population size, age and sex composition, and hunter effort as received from moose observation data ( pellet group counts, and from regular surveys of forest damages (Swedish National Forest Inventory (SLU) and ÄBIN (Skogsstyrelsen)). We will also use data from aerial counts of moose ( 4000 moose observations) to test the hypothesis that wolf presence is linked to a lower density of moose and/or harvest. Aerial counts ( ) have been conducted in 5 counties to achieve data on moose population size and composition. For hypothesis 2 we will use data from both the Swedish National Forest Inventory data and ÄBIN which include vegetation indices with detailed data of forestry actions and browsing damage in combination with indices of moose density. We will use GLMM to assess the strength and direction of the temporal and spatial relationships between the following variables: (1) wolf density and duration from census data (snow-tracking and DNA-analyses); (2) moose density and harvest data; (3) human impact, measured by forestry actions (clearing, thinning, final felling, afforestation); (4) forage availability, measured as cover of tree and field layer species; and (5) the level of moose browsing damages made to commercially valuable forest plants. 7 / 33

8 C. National scale - estimating the potential for future wolf population growth and trophic cascades We will estimate the potential for variable future sizes of the wolf population to have significant impact on several trophic levels of the ecosystem in Sweden. Earlier derived ecological data from VHF/GPS-collared Scandinavian wolves (n=164) will provide empirical estimates the biological level of saturation of the wolf population 17 over a region of south-central Sweden (main area for current and future wolf distribution 32 ). Next, we will model how the alternative scenarios of wolf population sizes at this geographical scale may affect the size, density and the potential harvest of ungulate populations (including moose, roe deer, fallow deer and red deer). From this we will model the consumption of biomass of valuable tree species from ungulate populations and will in turn be compared to both the kg biomass and the number of young trees consumed by forest management (pre-commercial thinning, thinning and final felling and limited to the sapling growth stage, i.e. the growth stage consumed by ungulates). As a basis for these calculations we will use simple descriptive estimates from published data on forest production 31 and from forage biomass consumption of ungulates. The strength of this modelling approach lies in the quantitative assessment of impact on the forest ecosystem of both 32 top predators (wolf and humans) and thus on the ecological functionality of wolves in an ecosystem with strong anthropogenic impact. Plan for scientific deliverables Results will be deliverable in high quality peer-reviewed journals including Open Access: 2 publications from subproject A, 2 publications from subproject B, and 1 from subproject C. Because the data for A and C are already available 2-3 manuscripts can be submitted already within the first two years. For subproject B which requires data compilation we plan for scientific delivery during year 3. The results will also be published as popular science articles in applied journals that are read by forest owners and NGOs (Skogseko, Svensk Jakt, WWF EKO etc.) and made available at Skandulv s (the Scandinavian Wolf Research Project) website ( National and international collaborations 1.

Description of the potential societal value of the research and a plan for communication with stakeholders/end users (max characters)* Societal value of the research question and planned communication with stakeholders Sustainable use of natural resources This research project directly relates to the sustainable use of natural resources in terms of linking the most important game species in Sweden (moose), to sustainable use of forest production and to the re-colonization and conservation of an iconic and endangered top predator (wolf). It is also highly relevant to the society because it directly deals with biological diversity, the biological capacity for production of moose and forest, as well as the economic, social and cultural values related to moose hunting. This research project is also of relevance for forest production and management because the return of wolves to the Swedish ecosystem are likely to impact on both population density of moose and on their spatial utilization of forest stands and thereby also the survival and quality of young and commercially valuable forest plants, e.g. Scots pine. Environmental goals This project relates directly to 2 ( Levande skogar and Ett rikt växt och djurliv ) of the environmental goals decided by the Swedish government 1. In the broadest sense, the focal species of this research project (humans, moose, wolves, forest plants) and the ecological processes (harvest, predation, herbivory) are all important components of the biological diversity. More specifically, there is a strong link between density of ungulates and biological diversity of forest plants but also in terms of the conservation status of the wolf. In their new and recently published policy document for the management of Swedish wildlife the Swedish Environmental Protection Agency 2 (SEPA) states that wildlife.should be managed in a sustainable way and that this includes ecological, social, cultural and economic aspects. A sustainable wildlife management means balancing between the use and conservation of wildlife species. This policy also states that wildlife management should be based on an ecosystem view, i.e. with respect to how humans, wildlife species, and the landscape they live in and how they affect each other. Conservation of a vulnerable species 9 / 33

10 This research project is relevant for the political decisions on conservation and management of wolves on both a national and international level. The wolf is classified as a vulnerable species in Sweden 3. On numerous occasions during the last 10 years there has be a heated controversy between Sweden and the European Union (EU) on how the Scandinavian wolf population should be managed within the frame of the habitat directive 4. EU has at multiple occasions questioned wolf management in Sweden and threatened to report Sweden to the EU-court for not following the habitat directive. On the national arena the SEPA decisions on license harvest during several years has been appealed by NGO s to a number of court instances at various levels. These political and juridical affairs have resulted in that the wolf population continues to grow significantly larger than the size considered as having favorable conservation status (FRP) by the SEPA (270 decided in October ). Also linked to this is the fact that some scientists and proponents of large carnivore conservation claim that the size of populations should not only represent the demographic and genetic viability, but also that functional ecological role of the species in the ecosystem is fulfilled. The results from the suggested study will help to guide what conditions should be met to achieve such an objective. Two-way communications at three levels We will apply a three-level strategy for a two-way communication of our results with stakeholders and the society. The relevant stakeholders that are interested in results from this project are the SEPA, County Administrative Boards within the current and future wolf range, hunting organizations, forestry companies and private forest owners, and nature conservation organizations (for example WWF, Swedish Society for Nature Conservation, Swedish Carnivore Association). National level three existing channels for communication At the national level we will make use of already existing channels established by the Skandulv research group since 1999 for communication of results and feed-back from stakeholders. First, Skandulv annually arranges a three-day work-shop with people invited from the ministry of environment, central managing authorities (SEPA), the regional management on the county level (County Administrative Boards) and NGO s for communicating new research results and to discuss management-related issues. Also national and regional management authorities from Norway and Finland are attending. Second, educational presentations for the Wildlife Management Delegations (including members from all interest groups and politicians) of the County Administrative Boards are already, and will also during this project be given by the three applicants annually. This enables direct communication with the delegates who set comprehensive guidelines for game management and approve county Wildlife Management Plans. Third, our results will be reported at the annual carnivore symposium held in Vålådalen where managers from national and regional authorities, journalists, NGO s, other stakeholders and researchers, meet to be updated on the latest research and management actions performed. Regional level reference group At the regional level we will establish a reference group for communication and feedback on our ideas, methods and preliminary results. This reference group will consist of management personnel from several of the national authorities and stakeholder organizations directly involved. We have been given a preliminary approval by the following persons and organizations; Christer Pettersson, SEPA; Maria Falkevik and Johanna Wikland, County Administrative Board of Värmland and Örebro; Krister Kadell, Swedish Forest Agency; Gunnar Glöersen, Swedish Association for Hunting and Wildlife Management; Michael Larsson, Storaenso, and Mats Forslund, WWF. This group also acknowledge that these questions will be given high priority by the research community. Local level public meetings At the local level we will annually arrange information events where the public can take part of our results, ask questions, and discuss our approach and findings. All three applicants are also regularly invited to present our research at meetings arranged by for example local hunting organizations and public information events. The main applicant of this proposal are responsible and initiative takers for a high number of publications and public information events. During the last two years the three applicants have together participated, and often led, more than 100 information events ranging from single hunting districts to conservation groups and meetings with regional and national management authorities. Finally, at the Skandulv website there is currently >300 publications listed including results from the research project and which most are available as downloadable documents. These publications includes research results ranging in type from pure peer-review articles, to reports and investigations as assigned by national management authorities to Skandulv, and finally to popular science articles. This diverse and well established network of communication channels linked to the proposed research project in combination with the reference group and arrangements of public meetings will assure an involvement of stakeholders and the public during the project.
